Hello guys,

I’m new to ruby on rails and I’ve been given a question by my manager to  
do the following task below but i can’t seem to find the command or go  
around doing the task. so i’m wondering can anybody help me here?  
Here’s the task below:-

## Question

Write a batch file or ruby script file to detect large mail folders on  
the server.

1. Write a batch file to list all \*.pmm files under f:\home folders  
(including subfolders) into a text file, say, bigmail.txt

2. Use ruby to scan the bigmail.txt file and output only those lines  
with file size more than 100MB, again redirect the output to a text  
file, say, bigpmm.txt

I’m not sure how to go about doing the above. Can anyone assist me? My  
programming skills are poor and yet i can’t find the way to solve the  
question above.

Thank you and appreciate the help a lot.
